GENERAL DESCRIPTION
The Z86160 is a member of the Z8^® single-chip
microcontroller family offering a unique architecture that is
characterized by Zilog's 8-bit microcontroller core.
This CMOS microcontroller features fast execution,
efficient use of memory, sophisticated interrupts, input/
output bit manipulation capabilities, and easy hardware/
software system expansion along with low-cost and
low-power consumption.
For applications demanding powerful I/O capabilities, the
Z86160 fulfills this with custom I/O, specifically tailored to
meet the needs of set-top requirements.
Four basic address spaces, the Program Memory, Data
Memory, 236 General-Purpose Registers, and 512 bytes
of protected RAM, support a wide range of memory
configurations. The protected RAM is mapped into data
memory.
To unburden the program from coping with real-time
problems such as counting/timing, and serial data com-
munications, the Z86160 offers two on-chip counter/timers
with a large number of user selectable modes, and an
asynchronous receiver/transmitter (UART) (see Block
Diagram).
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
